Taipei, April 28 (CNA) The Taipei City Police Department apologized to two journalists at a local daily on Monday evening for roughing them up as police tried to disperse people occupying a main thoroughfare in downtown Taipei in the early hours of Monday morning. The Apple Daily said police beat reporters Yeh Yu-pu and Chang Chun-hao with batons and dragged them away to prevent them from taking pictures when police began to carry protesters away from Zhongxiao West Road. The protesters were expressing their opposition to Taiwan's controversial fourth nuclear power plant. The city's Police Department said it regretted the injuries the two sustained and the damage to their glasses and cameras and promised to compensate them for their losses. Police said they would conduct an investigation into the incident and if the police officers involved acted inappropriately in carrying out their duties, they will have to take responsibility. The department also said that 30 policemen were injured during several rounds of dispersal operations. (By Lin Chang-hsun and Lilian Wu)
